Question about 1987 Chevrolet S-10 Pickup
I need some sort of written directions on how to rebuild a transmission for a chevy blazer S 10 auto. (1987)
A transmission shop should be able to order one pre-built for you and install it, or even order the correct kit and parts to rebuild your old trans. This can cost about $2000 or more, either way you should get a warranty in letting them do it for you. Most shops may not want to just install a used one from a junkyard without a rebuild since they cannot warranty it.
You can still get aftermarket rebuilt transmissions for this application from many sources if you want to install it yourself and save the shop costs. You can save yourself about half or more of the overall cost of the shop doing it if you want to rebuild it yourself. But this is not a job for anyone without plenty of mechanical experience and common hand tools.
Rebuild & master kits for the 700R4 are available from a wide variety of aftermarket sources. Be sure to read the transmission ID number correctly to properly identify your model year. 1987 models may come with or without an internal 'auxilliary valve.'
Get the ATSG book (and the related update book) for your specific model year, available online. The update book lists important changes and modifications made in mid production applicable by the julian date code of your specific transmission. There are DVDs available too that are very helpful in addition to the books visually showing you each step of the teardown and reassembly procedures. These are all averaging about $25-30 each. Study this material first before digging into your transmission.
You can improvise some of the required special tools, but the KD Tools universal spring compressor is highly recommended at about $100. Heavy duty curved tip snap ring pliers are also recommended with the other common hand tools needed.
The books and DVD will refer mostly to the V8 setups as the clutches come in a variety of combinations pending application. Pay very close attention to the order parts came out (take plenty of photos). The V6 versions are slightly different again from the V8's in the o.e.m. V6 setups will have fewer total clutches and steels in the stacks.
Your local transmission shop should be able to answer some questions if you get stuck, but don't expect them to teach you how to do everything. For a few bucks, most shops will gladly help you setup the correct clutch stacks and clearances for you to reassemble at home. I would also suggest letting the shop install all the new bushings for you since it is critical to keep them straight and some have to set at specific depths. This should only cost about $20-30 if you take the individual parts in to them.
Take your time and follow each step of the rebuild procedures. Keep everything very clean as you go! Follow the regular instructions and procedures in the general repair manuals for reinstallation and refilling of the transmission.
Good luck, it can be done.

Good luck. I have a1987 s10 truck, transmission went out (standard 4 speed). There were very few places that even had a rebuilt transmission for my truck. One place was going to rebuild it, then found that many of the parts were not being built any longer. Called the chevy dealer and found this to be true, parts were discontinued.
